PROCESS O1 MANHOLDING Application fled September 28, 1927. Serial No.229,866.

My invention relates to the forming of manifolding copies in a'series ofsuperimposed forms or pieces of paper which shall be perforated as wellas imprinted with a coloredl impression, so as to be entirely safeagainst alterations.

It is my object to employ in the marking of manifold copies a type faceor reciprocating perforating pin which penetrates all of the sheets uponwhich the manifold impression is to be made, and to pigment or colorcause of its tendency to smudge, wear out,

make indistinct copies and limit the number of copies that canbemanifolded. In'stead of thls, and instead of using manifoldin clothor-printing cloth, I employ a kind 0 hard coating,

coated paper which has a particular quality that suits my process. Thispaper is coated on the side which will lienext above a iece of paper tobe marked with anon-smu ging and contains those elements which gree, andshouldhave a color which contrasts markedly with the color of the pieceof paper that is to be marked. In the paper trade, a stock grade of thistype of paper isknown as-glazed coated paper, and is readily obtainable,and demonstrates the process.

I have found that if such a permanently coated paper or other types ofcolor coated paper where the color coat is not smudgy or easilydislodged, is employed, that I can by using a perforatmgfipin or a typeface formed of pins, readily slodge suflicient of the color coating froman upper. coated web to igmjent the walls of the oles made in the owerweb by the perforating element.- While not as brightly pigmented as werecarbonized paper used, or a printing ribbon or the like, the color isnot smud at all,

and while it can be erased, it remain which are coate give a permanentlike finish to the paper. The coating is. preferably of such a type thatit will be brittle to a certain dequite permanently about theperforations so as to color them and render the reading of them easy.

The best mode of practicing my invention is to use a paper coated on theunderside with color and left white or with a pale color on the topside, with the top side imprinted with whatever form is being used. Itis not practical in ordinary industrial uses to employ manifold slipsand forms which are coated with carbon paper finish on the undersidebecause of the smudging of anything with which such a form comes incontact. With the use of the special coating or anyother relativelypermanent color coating, I am, enabled to do away with the interleavingof any copypaper whatever between the forms in a manifolding machine,and it also enables me to make many more copies at one writing.

'The most expensive element in the use of manifolding machines to-day isnot the rinted paper issued thereby, but the caron paper which is used.Also, when a-large num er of forms must be made as copies, there'willhave to be twice as thick a bundle for the type to act upon as would berequired, were it ractical to use form sheets if on the back withremovable carbon.

Thus my invention eliminates the cost of carbon sheets, makes itpractical to form a larger number of copies at one writing than in thepast, and it makes good legible copies throughout.

I accom lish my objects'b that certain process to pointed out in etail,and for the use of which a typical mechanism will be shown anddescribed.

y process can be employed with a typewriter having type faces formed ofpointed pins spaced from each other andarranged in the shape of adesired character or letter. It can also be employed with a-stylushaving a reciprocating point that is operated somewhat after the fashionof a flexible shaft dentists tool. a

I have shown, however, only the typewriter mechanism which will sufiiceto explain the nature of my invention.

I have illustrated a typewriter 1 mounted to move to and fro and forwardand back on'a frame 2. A storage roll for manifold paper webs, such asprinted form, is shown at 3. This paper will preferably be coated han onthe back with a color coat. I have illustrated one of the webs at 3, ashaving a color coating 3?. As stated, this color coating should beof'non-smudging type, and preferably should be a coating of a colorwhich strikingly contrasts with the printed form face of the paper, orif not printed, the color of the face of the paper upon which writing ortvping is to be done.

T e typewriter will have its type arms as at 4 equipped at the ends withpins 5 driven into the ends, which pins carry type bodies 6. The typebodies 6 have each a set of pins 7 which are sharp pointed and arrangedin the shape of the desired character or letter. They will normally beheld in the type body by means of Babbitt metal.

Mounted on the typewriter and moving therewith I provide an abutmentplate 8 against which the type bodies will strike,

said abutment plates being arran ed to overfolding machine. The pins ofthe type are provided clearance by a notch 8 in the plate. The paper islaid across the platen of the machine and held down as by the usualclamp bar 9 of the Elliott Fisher machines, and the usual ribbons 9employed for the top web.

As the ty manner, stri ing the selected type arms down against thepaper, the pins will penetrate a of the forms. Since the forms have onthe usual ribbon guide 0 the mani ewriter is operated in the usual'" 1.A process for manifolding,,which consists in'assembling to ther a pileof paper webs of which the bac of an uppermost web is coated with anon-smudgi passing a pin through the pile, with the result of dislodgingpartlcles o the color coating and depositing them around the walls ofthe hole perforated in the paper next beneath said coating.
